Thanks Al,l I got that file Ben suggested installed it same result an error like before,so I ran it into a new folder and found it never had a named folder of its own, I gave itone and put it in trainset all is OK now no more error notice :O)

Hi Rick, I've just tried re-loading File ID 20951, which is the one I usedto install the tail lamp into my Trainset Folder.It defaults to the old C:\ drive so you must change this when installingthe file, I would suggest you look in your C:\Program Files\MicrosoftGames\Train Simulator\Trains\Trainset Folder and see if there is a foldercalled BR_MK1_Tail_Lamp.I don't use Windows 7 to run MSTS as my computer is dual booted andgo into the XP partition to install any MSTS Files and I have to be carefullon installing certain files to make sure that they are installed correctly.
